PCG/PC SA 235 Manual 14-03-2012
General
Thank you for purchasing this waterproof SATEX precision weighing scale !
This scale is equipped with reliable technology and has user friendly operational software.
You will use it many times and it will prove itself to be an easy, very speedy and accurate tool.
If any questions raise that are not described in this manual, please address yourselves to your SATEX supplier,
have a look at our website : www.satex.nl or send your questions per email to : [email protected]
Application, waterproof, HACCP
The water resistant SA 235 precision scale is designed for :
- use in wet and damp condtions
- very accurate (high resolution reading) and very fast weighing
- check weighing with 2 settable weight margins
- counting pieces
The scale may be used without problems in very humid and moist conditions.
The scale fulfils the requirements of Norm EC 60529:2001, sealed to IP 67: submerged in clean water during
1 hour at a depth of 1 m, penetrating water will not cause malfunctions.
The stainless steel exterior of the scale is designed according to the HACCP principles for food safety.
The SA 235 is designed for internal weighing only. The use of the scale is not permitted for commercial purposes.
Safety
Please read this manual thoroughly before start using the scale.
The supplier does not accept any responsibility if the guidelines of this manual are not observed.
Before any work is done on the scale, power connections from the mains adaptor and the internal battery
should be interrupted. Warranty is void if the scale is opened anyhow.
The instrument fulfils the requirements laid down in the EG regulations 89/336/EWG and 73/23/EWG for
electromagnetic compatibility.
Exceeding of the maximum values, laid down in these regulations, must be avoided.
The instrument is isolated according to class 2:
Electrostatic discharges may cause fatal damage to the scale and should be avoided at all times.
A.o. a proper earth connection of the scale and the place of erection is required in such cases.
In case the 230 V excitation cable is damaged, or the scale is not working with the 230 V connected, the
scale should not be used any longer and sent for service to your supplier.
The built in sealed lead battery should, if it has to be replaced, be disposed off as small chemical waste,
not to be added to normal waste.
Maintenance
Except from regular cleaning with a slightly humid cloth and a not aggressive detergent, further maintenance
is not required.
However it makes sense to check the scale’s weighing accuracy with regular intervals, using accurate calibration
weights of class M1 at least. The scale may be adjusted by the user itself using accurate class M1 weights.

level indicator
Do not expose the scale to extreme temperatures. Caused by differences in temperature it may last until 10 minutes
before the reading of the weight is completely accurate.
Place the articles to be weighed carefully on the weigh platform. Prevent for bumping against and overloading of
the weighing platform. The loadcell down under it may be damaged seriously. Avoid long lasting loading.
Make sure you have a stable basis for the scale
Check, if necessary, the accuracy with an accurate calibration weight. Using the calibration procedure the scale may
be re-adjusted.
At first start up the built in battery may be not completely loaded. Re-load the battery by leaving the scale for at
least 16 hours with a connected mains adaptor. If not used the battery should be recharged every 3 month.

Check weighing
( check weighing with 2 settable weight margins)
Two weight margins can be entered: the down limit and the up limit.
If the weight value is:
- higher as the up limit, Led "HI" lights up
- in between the up and down limit, Led "OK" lights up
- lower as the down limit, Led "LO" lights up
This weight control works for a gross, as well as for a tared (net) weight reading.
In the user mode a "beep" sound may be connected to the weight margins.
The accuracy of the margins is based upon the High Resolution weight reading, even if this is not the
actual selected weight reading.
Note:
The check-weighing function cannot be active in the piece counting mode. Both function cannot be active at
the same time.
First switch off the selected mode (key
> 2 sec.) and switch off the scale. Switch the scale on again and
select the required mode.
Before entering the weight margins, the weigh platform has to be empty

The SA 235 features a simple piece counting program.
Depending on the capacity of the scale, articles
may be counted with a minimum weight of:
If article weight is less, the counting will be mistaken !
It is advised with small articles to use a larger number
of articles for the reference weighing.

Repeat the adjustment procedure if necessary.
Errors and reports
The weigh platform is overloaded, a warning "beep" sounds.
Remove the overload as soon as possible.
Weight reading is gross negative. Zero setting and taring is not possible.
The scale has been switched on with a load on the platform and has set
zero with this load.
After that the load has been removed and now the weight reading is negative.
Switch the scale off and on again with an empty weigh platform.
The scale refuses a zero setting key command.
The measured weight value is outside the zero range (+ and - 2% of the
weighing capacity of the scale).
Zero setting with the tare key is still possible If necessary switch the
scale off and on again with an empty weigh platform: a new zero setting
will be executed.
It is not possible to switch on the checkweigh- or countfuncion.
If one of these functions already is active, it is not possibly to switch on the
other one. Switch off the active function with key
> 2 sec.
Switch the scale off and on again.
